Tales of Suspense has always been my go-to for how Tony and Iron Man should be depicted. I especially love the very earliest issues, when the armor was gray and then golden, though I acknowledge the superiority of the later more form-fitting designs.

Ultimo and the Mandarin made for an excellent story. It interests me how Stan had a penchant for giant robots. The Red Skull had the Sleepers, for example. I actually wish there were more Sleepers, with the next one revealed in a new, modern story arc, with the protagonist being Iron Man. I would love to think there were many more, each one worse than the last, each one programmed to activate on some specific future date. It would give Tony his own "Oh no it's Galactus" type story. One could argue that Cap should have this story, but there comes a point where Cap couldn't fight these things any way. He'd have to call in the Avengers. Iron Man could actually fight these things himself, though the battle would be harrowing every time.
